IRVINE, Calif., Aug. 16, 2017 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC)* today announced a new family of CMOS low dropout (LDO) regulators: the TCR4DG series. Consisting of general-purpose, single-output voltage regulators with on/off control input, low output noise voltage and low inrush current, the TCR4DG series is available in fixed output voltages between 1.0V and 4.5V – capable of driving up to 420mA.

Small ceramic input and output capacitors can be used with the TCR4DG series, making these devices suitable for mobile applications that require high-density board assembly, such as cell phones. The new regulators are offered in an ultra-small plastic mold WCSP4E package (0.645mmx0.645mm (typical); t:0.43mm (max)) and feature over-current protection, over-temperature protection, inrush current protection, and auto-discharge functionality.

"Mobile designs are becoming increasingly power hungry and are demanding high-current LDOs to fit inside compact designs," noted Talayeh Saderi, senior business development manager for TAEC. "With the new TCR4DG series, we're providing engineers with 400mA of clean, efficient voltage regulation in a small package – the 420mA LDO."

Key Features

  • Low drop-out voltage: VDO=193mV (typ.) at 3.3V-output, IOUT=420mA
  • Low output noise voltage: VNO=38μVrms (typ.) at 2.5V-output, IOUT=10mA, 10Hz<=f<= 100kHz
  • Fast load transient response (⊿VOUT =±115mV (typ.) at IOUT = 1⇔420mA, COUT=1.0μF )
  • High ripple rejection (R.R=70dB (typ.) at 2.5V-output, IOUT=10mA, f=1kHz )
  • Over-current protection
  • Over-temperature protection
  • Inrush current protection circuit
  • Auto-discharge function
  • Pull down connection between CONTROL and GND
